Embed video URL in rails application

hi,
I have a doubt which might be silly for experience Rails developers.
I am creating an application which is suppose to embed a video player with URL passed to it.
So while displaying i.e in XXX.html.erb file i am writting below code. Now problem is @movie.trailer is my variable in ruby code which has URL value . I want the embedded video to load with URL given by this variable value. Any suggestion how am i suppose to place the value of Ruby variable(@movie.trailer) in <embed src="variable_value"> part.

Note :- This code is working perfectly fine if i statically give value of URL.
Please help

The double quotes is telling Ruby that it is a string so what you are probably getting for src is literally "<% @movie.trailer %>". Try "#{<% @movie.trailer %>}" and make sure that @movie.trailer is returning a string, or just remove the double quotes. You could also place a method in the helper module to generate the string in the correct format.

edit:

If you want the results of the code to display you need <%= %>, but I don't think that takes care of the string concatenation.
